To me it looks like this game is obviously ment for the next generation PC, which means something like GeforceFX 5200 (my card) will be the minimum (will be able to run it with all options on off and lowest resolution) It will also probably need at least 2.4GH CPU and 512 DDR.

I'm expecting the requirements to be very high. Dawn of War doesn't have a very large number of units per side, but you need about 2GhZ to run it comfortably. It claims the minimum is 1.4 but if you try it on a 1.4 even a 1v1 will lag when you get near the pop cap. EAW is looking a lot bigger and more ambitious than DoW so I wouldn't be surprised if the requirements were higher.
